Bump compileSdk/targetSdk to 36 for Google Play 2025/2026 policy

Google Play requires new apps to target API 36 (Android 16) by Aug 31, 2025
and updates by Nov 1, 2025. Previous target 35 satisfied the 2024 deadline
but trips the 2025 warning in Play Console.

AGP 8.1.2 only officially supports compileSdk 34, so set
android.suppressUnsupportedCompileSdk=36 to silence the build-time error.
Bumping AGP itself is off the table for now — it retriggers the
rust-android-gradle 0.9.6 mergeJniLibFolders duplicate-resources bug we
already had to work around (see 0249f91 / 8875c74).

minSdk stays at 24 (no Play policy bump there yet).

Verified locally on AVD meow_api35 (arm64-v8a, API 35):
  - ./gradlew :app:assembleDebug green
  - scripts/run_local_emulator_tests.sh: 8/8 tests green
